Kinematics of the outer pseudorings and the spiral structure of the Galaxy
A. M. Melnik, P. Rautiainen
The kinematics of the outer rings and pseudorings is determined by two processes: the resonance tuning and the gas outflow. The resonance kinematics is clearly observed in the pure…
Model-based pattern speed estimates for 38 barred galaxies
P. Rautiainen, H. Salo, E. Laurikainen
We have modelled 38 barred galaxies by using near-IR and optical data from the Ohio State University Bright Spiral Galaxy Survey. We constructed the gravitational potentials of the…
The Bar Pattern Speed of NGC 1433 Estimated Via Sticky-Particle Simulations
P. Treuthardt, H. Salo, P. Rautiainen +1
We present detailed numerical simulations of NGC 1433, an intermediate-type barred spiral showing strong morphological features including a secondary bar, nuclear ring, inner ring,…
Dynamical modelling of a remarkable four-armed barred spiral galaxy ESO 566-24
P. Rautiainen, H. Salo, R. Buta
ESO 566-24 is an extraordinary barred galaxy, which has four regularly spaced spiral arms in blue light images. This type of four-armed spiral structure, which is rare among the sp…
